Another rarity from Premiere Opera (https://www.premiereopera.net/product/tobias-wunderlich-by-haas-bern-1961/?mc_cid=ed41b31483&mc_eid=f89f57520b): "Tobias Wunderlich" by Joseph Haas in a 1961 broadcast recording from Bern, Switzerland.
I see the score is currently for sale (https://www.musikantiquariat-stoeger.de/en/article/joseph-haas-tobias-wunderlich-oper-partitur-des-komponisten-1937-15433.html).
